The second motor 33 drives the height measuring plate 31 to perform lifting and height measuring motion through the second cam mechanism 32. The grating reading head 34 reads the height value of the height measuring plate 31 at different height positions, thereby measuring the height difference between the component to be locked and the locking component at the locking head 212. Specifically, the second cam mechanism 32 has the same structure as the first cam mechanism 23.

[0020] Combined with Figure 3 As shown, the clamping shaft mechanism 11 includes an intermediate transmission member 113, one end of the intermediate transmission member 113 is provided with a transmission shaft end, the other end of the intermediate transmission member 113 is provided with a roller mounting seat, the first clamping shaft roller 111 and the second clamping shaft roller 112 are fixedly mounted on the roller mounting seat, and the roller mounting seat is provided with an air avoidance groove 1131, combined with the attached Figure 3 As shown, the ruler portion 211 of the locking spindle 21 performs lifting and lowering motion in the air avoidance groove 1131. Specifically, the transmission shaft end of the intermediate transmission member 113 is connected to the output end of the third motor 12 through a coupling, and the third motor 12 drives the intermediate transmission member 113 to rotate. The intermediate transmission member 113 clamps the ruler portion 211 of the locking spindle 21 through the first clamping roller 111 and the second clamping roller 112, thereby driving the locking spindle 21 to rotate synchronously, and the locking spindle 21 drives the locking head 212 to absorb the locking accessory (not shown in the figure), and locks the absorbed locking accessory to the part to be locked (not shown in the figure).

[0023] Working method: When the locking machine head is in the high-speed working state, the lifting locking assembly 20 first drives the locking spindle 21 to lift, and the locking head 212 at the lower end of the locking spindle 21 obtains the locking accessory, and then the locking machine head moves to the part to be locked, and the height measuring assembly 30 measures the height difference between the part to be locked and the locking accessory, and the lifting locking assembly 20 drives the locking head 212 to move down to the part to be locked according to the measured height difference, and the locking drive assembly 10 drives the locking spindle 21 to lock;

[0024] When the locking head is in the high-precision working mode, the lifting locking component 20 first drives the locking spindle 21 to lift and lower, the locking head 212 at the lower end of the locking spindle 21 obtains the locking accessory, and then the locking head moves to the part to be locked, and the first motor 24 slowly drives the first cam mechanism 23. When the locking accessory at the locking head 212 is in complete contact with the part to be locked, the locking drive component 10 drives the locking spindle 21, thereby locking the locking accessory to the part to be locked.
